The EVs with V2G are just big batteries, nothing special. You certainly can charge your battery on the free power and sell it back during peak periods, and people are doing just that today. Just mostly using their 50 kWh household batteries rather than their EVs though, because V2G is still mostly science fiction unless you buy one of the few models of car that actually support it and have a compatible charger and inverter.

For V2G, its a simple feature that enables a car to participate and make money in the energy ecosystem. Govts have to standardize it for cars, just like mandating usb-c.

It has been standardized here, and we see articles about it in the papers for a few years. Yet only 2 or 3 cars on the market implement it and don't even advertise it, apparently still in trials or pushed aside for sexier features. I was under the impression it was not simple, as it requires more electronics and complexity in the car.

It its required by Govt (USB-C), all new cars would have this feature. It won't be optional.
